I wonder if the daughter feels the dad betrayed her by leaving.... Part of me thinks if Dad stayed and did end up injured or worse, in the daughter's eyes, that may seem more honorable than him leaving her there alone.
If I was faced with fighting five young males (one reportedly armed), I would know I am not going to win. Therefore I would have done the same thing, gone to get help. I guess a lot of people would prefer this guy got beat up (or worse). It's easy to judge while not actually having to deal with the situation. I would like to see how many of the armchair warriors would actually fight when faced with this type of situation (my guess most of them only think they would).
